Back when I 'raced' enduros, one enduro decided to hold a "...let's see who can ride the DEEPEST ..." in a creek, so one of the 'brain-surgeons' decided to mount a snorkel to the aircleaner of his bike, and run it up UNDER his riding jersey so the air-inlet was at the rear of his helmet, figuring he could ride in 4 or 5 FEET and win the... whatever...!

You can PROBABLY picture it - he rode in, deeper, DEEPER, then his whole bike was underwater STILL moving....

He must've 'washed-out' (GOOD choice of words?), because all-of-a-sudden he went over sideways plunging HIM totally under water, because, OF COURSE his snorkel attached him physically to the motorcycle....

i'm always in preservation mode, both body and bike, so those crossings spook me a little. can't see the bottom, you know the flow is going to push ya off your line, and you have to carry speed and momentum. when you do get across, whew, on to the next one.
